Product Information

  • Description

    Rifampin is thought to inhibit bacterial DNA-dependent RNA polymerase, which appears to occur as a result of drug binding in the polymerase subunit deep within the DNA/RNA channel, facilitating direct blocking of the elongating RNA. The known mode of action of isoniazid (INH) is to inhibit bacterial cell wall synthesis following activation by the bacterial catalase–peroxidase enzyme KatG in Mycobacterium tuberculosis. Ethambutol exerts its bacteriostatic activity by virtue of inhibition of arabinosyl transferase which is an enzyme necessary for the synthesis of bacterial cell wall
